"inotlier object of this invention 'is to'provide improved" means for controlling-l the force of the current asapplied 'rb the water wheel.' Y 5 Other objects will appear during the fol lowing detailed description of the device, and from the two sheets of drawings herewith made a part of this application.

In the drawings,

Fig. 1 illustrates the plan view of the current motor device in assembled form.

Fig. 1L represents a plan view kof the bracket ,for guiding the defiecting plane raising and lowering mechanism.`

Fig. 2 illustrates a side elevational view of Fig. 1.

1Fig. 3 represents a side elevational view of the current motor device disclosing operations thereof in sections. i

F ig. t represents a plan view of the forward end of the current motor device showing particularly the defiecting plane in relationship thereto.

Fig. 5 illustrates a vforward en d elevational view of the current motor device par-y ticularly disclosing the deflecting plane in relationship to the device and the means for raising and lowering the plane.

Numerals 1 and 2 designate sections of an ordinary fioat carrying thereon one or more undershot water wheels 3, 4 and 5, the wheels having blades 6, suitably formed for ythe purpose of a current motor drive. The float may carry one or more of these water wheels without affecting inany way the merits of this invention. Y

Suitable standards and journals are attached to the floats as at 7, 8, 9, 10, 11 and 12 for the purpose of receiving the spindles or shaft-s 18, 14, and 15 on the water wheels. To the spindles or shafts are properly geared the driving elem'ents 1d, 17, and 18, adapted to be utilized for mill service or otherwise. At vthe forward end of the oat a deiiecting'platelQis positioned,"the inner end of plate 19Kbei`ng pivoted or hinged to a section 20, which section is ysecurely Vfastenerdte thefioatrata point underneath th'e'water wheels, the section 2O being pretl lerab'ly of a narrow fiat strip of material of suitable width to oneedge of which, the inner endof the deflecting plate-19is pivoted for' hinged, l the other'edg'e of section 20 being adapted to receive an' vauxiliary deflecting yplate 21 suitably hingedA or pivoted thereto `and adjustable as -required. Deflecting plates 22 and 23V4 together withthe required' pivoted sections 21- and "25 are located in4 their proper relative positions with respect to the water wheels 4 and 5.

Means are provided for raising and lowering the deflecting plates, consisting of suitable mechanism attached as at 26 to the defiecting plate 19 and rextending upwardly through a suitable bracket 27 attached `to the fioat portions 1v and 2, and adapted to be lowered or raised as required by means of ar crank handle 28, the crank handle andY shaft being suitable carried on standards 29, attached in a proper manner to the fioats by means of bolts, screws, or otherwise. The crank shaft is adapted to receive a guard 30 having teeth adapted to mesh and cooperate with a ratchet gearing 31, slidably guided in the bracket 27. The forward deflecting plate 19 is preferably formed having a fan shaped forward portion and a rec` tangular shaped rear portion, the forward edge of the plate being preferably ona line with the extreme forward point or sections ofthe floats. The deflecting plate for the water wheels in the rear are of rectangular shape, however, as stated above, the'nuinber of water wheels included in this device would not aff-ect inateriallythe merits of the invention, the novelty and utility being confined primarily to the features disclosed and described in connection with'the forward water wheel 3,1 and the combination of features thereto,'including the defiecting plate 21, together with a suitable nieans'for raising and lowering the deflecting plane.

Loosely attached at the eXtreme forward points or side edges S2 of the floats, are

forwardly extending guards 33 adapted to be securely fastened together at a point 34. These guards 33 may be made of suitable material such as wood or otherwise, and will sey iio

function to protect the forward end of the lloat and deflecting plate from damage due to driftwood or otherwise. c

At the outer end 34E of the guard, the float 35 is preferably attached and suitably ar-l ranged, and weighted, so that the outer end of the guard may be partly submerged in order to better protect the float. An anchor cable 36 may be suitably attached to the lioat at points 37. Y

In operation this invention provides a current motor device having efficient means for regulating particularly the force of the current applied to the water wheel comprising a deflecting plate 19 formed in one piece, the forward end of which is fan shaped and does not extend beyond the outermost portion of the float.

It has been determined from experiment that the deiiecting plate as claimed and described herewith, is of the highest eiiciency7 adapted as it is to be easily and conveniently lowered and raised as required, by means of a suitable device.

` In operation the efficiency of the deflecting plate 19, vis furthermore greatly in- Y creased by its special pivoted connection ywith the fixed section 2O and the loosely pivoted auxiliary plate 21. These three deliiecting elements in lcombination form a highlysatisfactory means for regulating the force of the current applied to the water wheels particularly to the forward wheel.

Vhat I claim is: Y

In a current motor Vd evice comprising aV f1oat,`anf undershot wheel, and current de fleeting plates arranged to cooperate with the wheel, one plate` extendingV rearwardly ofthe wheel` and one plate extending or 4wardly of the wheel,'nieans for pvotably connecting the plates in spaced relationship nARvEY'w.
